KB2 Fibre-Optic Sheet Break Detector is designed to handle all kind of break detection.

With RGB-colour based detection it can detect different colours and then separate

wire/felt reflection easily from the paper.

Electronics located outside harsh environment

KB2 is very reliable even in a 100% humidity environment. While

the sensor head is exposed to high temperatures, the electronics

unit is mounted outside the machine hood using a fibre optic

cable. Fibre optics is available in lengths of 6, 9 and 12 meters.

The fibre optic cable is located inside the straight stainless

steel sensor head, which is 1.5 m long. Between the sensor

head and the display unit the fibre optic cable is located inside

the stainless steel flexible conduit. Purge air is lead trough the

conduit to keep the sensor head window open.

Easy to set up

KB2 unit’s large display and logical user interface allows easy

setup of the break detection by selecting the measurements

which give the highest signal difference. Break signal and

maintenance alarm are wired to the PLC or DCS. The 4–20 mA

current outputs for the signal levels are also available as an option.

Benefits

•• Non-contact optical sensor

•• Reliable in harsh environments

•• Air purge system

•• Not affected by dirt, steam or high temperatures

•• Fast break detection

•• Handles all paper and board grades and applications regardless of colours

•• Detects breaks even against a cylinder

•• Easy to setup

•• Large graphical display and logical user interface

•• Proven with hundreds of installations worldwide

KB2 Fibre-Optic Sheet Break Detection system is designed to

monitor sheet breaks in harsh environments. The non-contact

sensor is placed above or under the web to be monitored.

The system is proven with hundreds of installations around the

world, and set as a mill standard for many customers.

Thanks to the air purged system in the sensor head, keeping the

optics free from dirt, steam or high temperatures, KB2 is suitable

for installations in harsh environments or where the space is

limited. In addition to open-draw applications the breaks can be

detected against felt, wire, or even against a cylinder.

RGB Colour and IR measurement

KB2 has both, RGB or Infrared light sources to perform superiorly

with all paper and board grades and applications regardless

of colour. The RGB colour measurement can handle all

sheet, wire and felt colours providing reliable break detection.

The KB2 system is proven with hundreds of installations around the world, and set as a mill standard for

many customers.

KB2 Fibre-Optic Sheet Break Detector is the new generation sheet break

detector that with the latest RGB technology enables more light with

effective power LED. This allows longer detection distance and operation in high

ambient light condition. KB2 is the perfect choice for installations in unclean, steamy

and high temperature environments, or where the space is limited.

Fast break detection

KB2’s digital signal processing technology measures all signals

a thousand times per second. KB2 is immune to ambient light

changes by measuring the backlight intensity. The break detection

delay is very short, a minimum of 15 ms – with digital

filtration the user can select how many measurement cycles

should be used for break detection.

The AO845/AO845A Analog Output Module for single or redundant

applications has 8 unipolar analog output channels. The module

performs self-diagnostic cyclically. Module diagnostics include:

External Channel Error is reported (only reported on active

channels) if the process power supply that supply voltage to

output circuitry is too low, or the output current is less than the

output set value and the output set value > 1 mA (open circuit).

Internal Channel Error is reported if the output circuit can not

give the right current value. In a redundant pair the module will be

commanded to error state by the ModuleBus master.

Module Error is reported in case of Output Transistor Error, Short

Circuit, Checksum Error, Internal Power Supply Error, Status Link

Error, Watchdog or Wrong OSP behavior.

Features and benefits

• 8 channels of 4…20 mA

• For single or redundant applications

• 1 group of 8 channels isolated from ground

• Analog inputs are short circuit secured to ZP or +24 V

• HART pass-through communication
